1.2 - Russian Release

Released thanks to active participation of Sum Of Technologies.
Sum Of Technologies is one of the leading Russian expert in industrial automation, implementing
complete cycle of production and manufacturing
automation systems from the separate PCS and SCADA to integrated MES/MOM-level systems.
Industries Served: Mining and Metals, Oil & Gas, Pharmaceuticals and Biotechnology, Power Distribution, Pulp and Paper/Wood Products.
All Beremiz contributions are done as part of development of own
embedded solutions for industrial automation.

Release Candidate 1 - Jan 2017

This version collects all enhancements from Andrey Skvortsov, Sergey Surkov, Paul Beltyukov, and Alexander Shaykhrazeev over 2016 :

Support for wxWidget 3.0, still compatible with wxWidget 2.8

better i18n support

Russian translation

more examples, better documented

updated license headers and text files.

full screen editing (f12)

pedantic SFC editing

prevent connecting multiple wires on single block input in languages other than LD

fixed search in code (regular expression, case insensitive)

reworked about dialog (for better i18n support)

updated windows installer dependencies

enhanced variable and step/jumps renaming

Other enhancements from 2014 and 2015 include :

support for Makefile based projects (alias 'Generic' target)

WAMP connector (websocket)

SSL support with Pyro connector

variables trace buffering in python runtime

support for python runtime extensions

more PLC introspection for python runtime code

A lot of IDE and runtime bugs have been fixed since 1.1RC5. See beremiz hg log for details.

1.1 - Korean Release (2013)

Thanks to contributions from LinuxIT
and SSLab, Beremiz GUI is now translated into Korean,
and also supports Korean characters encoding for user inputs, and file paths.

Fifth Release Candidate - RC5

New lxml based internal data model representation.
Many queries initially performed in pure Python have been replaced by Xpath and XSLT stylesheets,
tremendously accelerating operations, specially with large programs.
XSLT stylesheets writing was made easy thanks to YSLT,
an incredibly powerful Y Language for XSLT.

This was latest Release Candidate. Final 1.1 hasn't been published.

Fourth Release Candidate - RC4

More fixes and optimizations.

Third Release Candidate - RC3

Fixes, cleanup and code refactoring.

Second Release Candidate - RC2

Half a year after RC1, RC2 comes with many bug fixes, but also new features.

CANopen support back again.RC2 re-introduces CanFestival extension in Windows
installer, for pedagogical purpose. CAN network is by default emulated through TCP.
Connecting to real CAN hardware requires rebuilding CanFestival for your specific hardware.
Commercially available CAN interfaces require proprietary DLL that cannot be distributed
without authorization.

Visible part of the refactoring of Beremiz extension mechanism.
"Plugins" became "Configuration nodes".
Extensions now provide either blocks, located IO, build system or connectors.

Search for text pattern

Across project and inside current POU:

Across library:

Automatic naming of instances

Avoids loosing time filling useless names when creating large POUS.

Beremiz workspace is now persistent

Interface layout is restored,
last opened project is re-opened,
opened tabs and traced variable are saved per-project,
and restored upon project opening.
A menu item let user reset workspace if necessary.

About beremiz

Free software for Automation

Beremiz is an integrated development environment for machine automation. It is Free Software, conforming to IEC-61131 among other standards.

It relies on open standards to be independent of the targeted device,
and let you turn any processor into a PLC.
Beremiz includes tools to create HMI,
and to connect your PLC programs to existing supervisions, databases, or fieldbuses.

With Beremiz, you conform to standards,
avoid vendor lock, and contribute to the better future of Automation.

Motivations

Despite of open standards such as IEC 61131, PLCOpen and CanOpen,
control engineers cannot deploy results of their engineering effort
in an heterogeneous environment. It is usually required to rewrite
your PLC program for each particular PLC brand.

The reason for this is that proprietary solutions providers do not
fully conform to standards, thus preventing interoperability,
harmful to their business model.

Furthermore, standards specification are necessarily non exhaustive
and leave some "manufacturer specific" freedom to the implementer.
Solution providers make great benefits out of those manufacturer specific details,
at the expense of the freedom of the end user.

The Beremiz Project fills the gap between those independent standards specifications,
by providing an integrated reference implementation of them.

Report bugs

If you've found (reproducable) bug, and want it to be fixed.
First search bugtracker, maybe someone already reported this issue.
If the issue is already described, you may add your examples or comments to it.

If the problem isn't described yet, then please check whether
it exists in the latest version of Beremiz from development repository.
If it still exists, then create new bug report for it.

Perfect bug report contains:

Exact steps to reproduce the problem, to make it easier for developers to fix it.

Improve translation

The easiest way for newcomers to help Beremiz project
without python knowledge is to improve support of your native language in Beremiz IDE.

Beremiz developers use Transifex, web-platform for translations. https://www.transifex.com/beremiz/beremiz-ide.
It is easy to use and is used by many other open source projects:
dpkg, Mercurial, Bitbucket, Fedora, XFCE, PulseAudio, Django and many others.
If your language is missing, request it on Transifex. It'll be added ASAP.

Current status of translation.

Update community wiki

Beremiz community wiki is here.
You are welcome to add/update information there.

Improve documentation

Another way to help the project is to improve current state of documentation.
For example, you can improve description of functional blocks stored in plcopen/Standard_Functional_Blocks.xml and Additional_Function_Blocks.xml.

Be aware, that use of any copyrighted material is not allowed.
